摘要： A keyboard device includes plural white and black keys 11w, 11b that rock according to a key depression/release operation. Positions of key support portions 13w, 13b supporting the plural white and black keys 11w, 11b in the longitudinal direction are set to be different from one another. The keyboard device also includes hammers 16w, 16b that rock with the rocking movement of the plural white and black keys 11w, 11b. The plural white and black keys 11w, 11b include drive units 11w1, 11b1 that drive the hammers 16w, 16b. The pivot centers of the hammers are located on the same straight line extending in the lateral direction. The drive unit 11b1 is located anterior to the drive unit 11w1. An upper-limit stopper 21 and a lower-limit stopper 20, which restrict the rocking movement of the hammers 16w, 16b, are provided to extend in the lateral direction.

摘要： In a key switch (10), an inner dome (Din) starts to deform once a distal end portion (21) of the inner dome (Din) comes into contact with a base surface (93a) after an outer dome (Dout) starts to deform. A thick portion (25) extending straight and having a uniform wall thickness in a click generating portion (CL) has the thickness less than or equal to the minimum thickness of a thick portion (23) of an after stroke portion (AF). The degree of inclination of the thick portion (25) with respect to a center line (C0) (direction of pressing) is larger than that of the thick portion (23) with respect to the center line (C0) (θc>θa). Before the after stroke portion (AF) undergoes large deformation, the click generating portion (CL) undergoes buckling to cause a sudden decrease in a reaction force and generate a click feeling.

摘要： A switch is constituted by a movable conductive portion and a pair of fixed conductive portions. The fixed conductive portions are arranged on a substrate, and are each constituted by at least one strip member. A first main conductive pattern and a second main conductive pattern are arranged on the substrate in correspondence with the fixed conductive portions. The movable conductive portion electrically shorts the pair of fixed conductive portions upon coming into contact with both of them. The strip members that constitute the fixed conductive portions each have a first end portion and a second end portion in the extending direction, and the end portions are electrically connected to the corresponding main conductive patterns.
